摘要
在相移数字全息技术中,分别采用二步算法、三步算法、四步算法及全息数字相减技术,实现了对相移数字全息图数字的重现.通过对比由于参考光束的相移误差在不同情况下重现像的质量,表明二步算法比已有的算法能得到质量更好的重现像.
In phase-shifting digital holography, with two-step, three-step and four-step phase-shifting recording methods here and use a method with digital subtraction of hologram to implement reconstruction of (phase-shifting) digital hologram. The influence of phase-shifting error on the quality of the reconstructed image in digital holography is compared in different methods. The (results) showed that the quality of the reconstructed image with the two-step phase-shifting method is better than the others.
